As JESUS went into the temple HE was upset and started to overturn tables of the money changers.
Mat 21:13 And He said to them, “It is written, ‘MY HOUSE SHALL BE CALLED A HOUSE OF PRAYER,’ but you have made it a ‘DEN OF THIEVES.'”
Mat 21:14-15 Then the blind and the lame came to Him in the temple, and He healed them. (15) But WHEN THE CHIEF PRIESTS AND SCRIBES SAW THE WONDERFUL THINGS THAT HE DID, AND THE CHILDREN CRYING OUT IN THE TEMPLE AND SAYING, “HOSANNA TO THE SON OF DAVID!” THEY WERE INDIGNANT
The religious people were outraged because JESUS healed the sick, and because of the praise of the children.
Mat 21:16 and said to Him, “Do You hear what these are saying?” And JESUS said to them, “YES. HAVE YOU NEVER READ, ‘OUT OF THE MOUTH OF BABES AND NURSING INFANTS YOU HAVE PERFECTED PRAISE’?”
They said to JESUS, “DO YOU HEAR WHAT THESE ARE SAYING?” They were willingly ignorant at the theft and desecration of the temple maybe because they got a share of the proceeds?
But I like what JESUS said, ‘OUT OF THE MOUTH OF BABES AND NURSING INFANTS YOU HAVE PERFECTED PRAISE’! Children are completely dependent on their parents, when they are hungry they cry out, when they are tired they cry out, when they need changing or just need to be held they cry out!
Psa 8:2, OUT OF THE MOUTH OF BABES AND NURSING INFANTS YOU HAVE ORDAINED STRENGTH, Because of Your enemies, That You may silence the enemy and the avenger.
There is strength when we cry out to the LORD as little children do. We should always have true humility when coming to the FATHER for anything, HE has an ear for the humble, but pride kept the religious men from seeing the obvious.
Psa 10:17-18, LORD, YOU HAVE HEARD THE DESIRE OF THE HUMBLE; YOU WILL PREPARE THEIR HEART; YOU WILL CAUSE YOUR EAR TO HEAR, (18) To do justice to the fatherless and the oppressed, That the man of the earth may oppress no more.
